Recognising that the prospects for a military order from the British services to have become very limited, the company decided to re-orientate the Ultra-light to conform with the preferences and needs of civil operators instead.

Further requirements for the prospective light helicopter included a flight endurance of one hour along with the potential for carrying light cargoes such as fuel and tools, as well as stretcher-bound wounded troops. An initial request for a rear-facing observer's seat was present early on, but was
